Need help connecting Samsung Blackjack to UMTS network overseas

I have an unlocked Samsung Blackjack phone which I have taken overseas
to Africa.

I have installed a SIM card from a local provider and am using the
phone with this provider's network. I can make phone calls and access
the provider's GPRS system with no problems. However, I am unable to
connect to their UMTS (ie: 3G) system. (The provider does indeed have a
UMTS system installed and functioning.)

In the header bar at the top of the phone's screen I only get a "G",
indicating GPRS connection capability. I do not get a "3G".

Any suggestions on how to get this phone to connect to a UMTS system
other then Cingular's would be most appreciated.

The provided says it is 1922.40 MHz.

I don't think you are going to be able to connect to their 3G/HSDPA
network using your BlackJack. In fact I think the only thing you are
going to get is GPRS, and if your get Edge I would be surprised. Sorry
that this isn't much help

This is the only thing I could come up with on their 3G Network and
nothing indicates International

I don't believe that the BlackJack includes that particular frequency.

It should include UMTS for the 2100mhz band, the highest 1900 band is
probably 1910Mhz.

Do you know where I can confirm this? For example is there some
technical documentation or a web page that states the frequency bands
that the phone operates at?

It seems strange that the operating frequencies for UMTS would not be
standardized world-wide and why would Cingular/Samsung make a phone
that would only work in some countries and not others? Why wouldn't
they make a phone that covered all 1900 bands world wide? So I'd like
to look into this a bit more before I give up on the Blackjack
altogether.

You can try phonescoop.com for the specs of most phones.

From the wikipedia entry on UMTS:

"In the United States, UMTS is currently offered by Cingular on 850MHz
and 1900MHz, due to the limitations of the spectrum available to them at
the time they launched UMTS service...

"Because of the frequencies used, early models of UMTS phones designated
for the US will likely not be operable overseas and vice versa..."

Cingular is a US-based carrier who sells US-centric phones.

Cost and complexity. It's only in the last few years we've seen phones
that had all four GSM voice bands. Previously it was more typical to see
different versions of the same phone adapted for the market it was sold in.

Good luck. When T-Mobile USA rolls out UMTS later this year, it will be
at different frequencies than Cingular- 1700 and 2100MHz, so T-Mo and
Cingular versions of the same phone won't even be interoperable for UTMS!

What Are The Supported Frequency Bands For My BlackJack (SGH-i607)?

Network Capability

* Transmit / Receive Range:
o GSM 850 MHz: 824.2 MHz - 848.8 MHz
o GSM 1900 MHz: 1850.2 MHz - 1909.8 MHz
o WCDMA 850 MHz: 826.4 - 846.6 MHz
o WCDMA 1900 MHz: 1852.4 - 1907.6 MHz
o UMTS 2100 MHz: This device also contains 2100 mHz DCS
functions that are not operational in U.S. Territories.
o Bluetooth 2400 MHz: 2402.0 - 2480.0 MHz


FAQ from Samsung.com

Unfortunately its ASP, so there is no direct link to it...but if you go
the FAQ section

http://www.samsung.com/support/faq/faqs_index.asp

Select cingular, then the BlackJack from the drop down menu, then in
the FAQ listing, select "Network" and it will show you the available
frequencies. This should be fairly standard for Samsung phones in
their FAQ section.

On another note regarding why some phones do some things, and some
don't do other things. One of the main reasons that phones work in
some world wide markets and not others deal with FCC restrictions in
the US. the 900mhz band is an open band, whereas in the EU and other
areas its designated for cell phone use. the 850 mhz band is devoted
to cell phones in the US. The same is true for the higher frequencies
as well.

So where you are, there may restrictions regarding using what is
considered the UMTS band in the US and other places. It would be
extremely difficult, and time/power consuming for a phone to search all
possible frequencies.

As far as Samsung goes, Samsung creates phones that the carriers want.
All of their phones, except for a few, in the domestic market (US) are
sold locked and branded for a carrier. One of the exceptions is the
SGH-D900. Which is an OpenGSM phone, sold unlocked and nonbranded.

You could start at http://en.wikipedia.org/wiki/UMTS

Well, I guess that confirms it. The Blackjack won't operate on the UMTS
network where I am. By the way I am in Libya, the provider is Libyana.

What is really frustrating is that the provider operates their UMTS
network at a nominal frequency of 1900MHz, and the phone is advertised
as also capable of operating at a nominal frequency of 1900MHz. I had
checked this before I bought the phone. I don't think Samsung or
Cingular can expect the average consumer, like myself, to do anything
more then this.

But evidently even if the nominal operating frequency of the phone and
network match it doesn't mean the actual operating frequency of the
phone and network will match or overlap. **This is an obvious problem
for consumers.** How can the phone manufactures, service providers, and
the organization that defines the UMTS standard not have realized this.
It needs to be corrected.

After thinking about this for a few hours I decided not to give up on
the Blackjack quite yet.

There is one possibilty I want to explore:
Is possible to change the frequency band of the phone?

I was looking at some newsgroup posts and they mentioned a code
*#1546792*#. I tried this code on my phone and it brought up a menu of
configuration options. Some of the menu items require a password to
access. I don't have the password but I am thinking that perhaps one of
these password controlled menu items accesses an area where the UMTS
frequency band can be changed.

Does anyone know anything about this?
